WTEB-ELEVATING APPARATUS.

To'aZZ whom it may concern: A

Be it, known that I, GEORGEFRANKHN VAN BEUNT. a citizen of the United States, residing at Kewanee, in the county of Henry and State of Illinois, have invented `certain new and useful Improvements in Water- Elevating Apparatus, of which the followingis a full, clear, concise, and eXact description.

This invention relates to apparatus for elevating fluids from one level to another, and more particularlyto such apparatus for elevating water from a well, cistern or other receptacle to outlet points variously located.

The object of this invention is the provision of an efficient self-contained iuid elevating apparatus'o few parts, readily and easily assembled.

In accordance with the presentinvention, there is provided 'a cylinder having a iuid inlet and within which is a ioating reservoir. The cylinder is provided with a fluid outlet pipe having communication with the oating reservoir, and with air inlet and exhaust valves controlled by the oating reservoir. l

For a more complete understanding of this invention, reference should be had to the following description, taken in connection with the drawings, wherein:

Figure l shows a longitudinal cross-sec-` tional view of the uid elevating apparatus containing one embodiment of the present invention i Fig. 2 is a perspective offthe air inlet and exhaust valves and their connections to the `fioating reservoir:

Fig. 5 is a sectional view on line 5-5 of Fig. 1, showing the position of the weights when the Hoating reservoir is practically empty and in its raisedV position;

Fig. 6 is a view showing the position of the weights when the floating reservoir is full and in its lowered'position; and

Fig. 7 is a view showing how the roller guides for the weights are mounted.

Referring to the drawings, the. cylinder may comprise a metal tube 10, in the lower Speeieation o f Letters Patent.

end of. which is a foot valve 13, securely attached thereto by means of a threaded bush-A ing 12 and an internally 'threaded ring 11. The foot valve 13 serves as a fluid inlet for the cylinder. In order that there may be a tight vfit when the valve is seated, a packing ring, preferably of leather, may be provided. The upper end ofthe cylinder is closed by means of a head 15, secured to the pipe 10 by'means of an internally threaded ring 16. The head 15 is provided with three openings, an air inlet 17, to the upper end of which is attached a pipe 20, leading to a supply of compressed air, an air exhaust 18 and a uid outlet 19, to the upper end of which is attached a` pipe 21, leading to any desired location.

An air inlet valve 25 of the ball type flts into the lower endof the opening 17, and an exhaust valve 26 fits into the lower end of the opening 18. A valve lever 29, to one end of which is pivoted an arm 31 for con-l trolling the ball 32 of the inlet valve 25, is pivotally mounted in the lower {end of a downwardly extendingarm 27, foried integrally with the body of valve 25. A similar'- valve lever 30, to one end of whichiis piv` oted the valve face 33 of the exhaust valve .e5

provided with a rod 34 for guiding valve face 33 to its seat, is pivotally mounted in the lower end of a downwardly extending arm 28, formed integrally with the body of exhaust valve 26. The inner or free ends of the -valve levers 29 and 30 are U-shaped and pass through openings in a yoke piece 35. so that vertical movement of the yoke 35 imparts a simultaneous movement to the valve levers 29 and 30 for opening one valve and closing the other.

Within the cylinder there is provided a can 40 which, in the operation of the apparatus, is adapted to rise and fall and to be filled with and emptied of a uid, thereby serving as a oating reservoir. To the up' per edge of and on the inside of the can 40 are attached two rings or bails 39. upon each of which is mounted an upwardly Aezt-- tending slotted member 41. Within the slots of the members 41 slide the ends of the yoke 35.v The construction of the Slotted members 41 and the ends of the yoke 35 is such that the can 40 may rise or fall for a considerable distance without affecting the position of the yoke 35, and therefore the air inlet and exhaustvalves. The legs of the U-shaped end ofA valve lever 30 extend to points immediately over the edge of the can 40, so that when the can has risen suiliciently, the rings 39 attached thereto engage the extreme ends of those legs to start the movement of valve lever 30 about its pivot point to open the exhaust valve. l Into the lower end of the fluid outlet opening 19 is secured a fluid outlet pipe 42, which extends through an opening in the yoke 35 down into the can 40, terminating at a point near the bottom thereof when the can is in its raised position, as shown in full lines in Fig. 1. Upon the outlet pipe 42 are mounted two spiders 43, one near the top and the other near the bottom, upon the ends of the arms of which are mounted rollers 44 for guiding the floating reservoir.

In order to assist the floating reservoir 40 in the control of the air inlet and exhaust valves, there is provided a system of weights, which in the operation of the fluid elevating apparatus are alternately supported by the floating reservoir and by the outlet pipe.I

This system of weights may be made up of sets of six balls 45. The means of supporting each set is the same and is such that in the downward movement of the floating reservoir 40. the balls are shifted from a support on the fluid outlet pipe 42 to a support moving with the. reservoir 40, and in the upward movement of the reservoir, the balls are shifted back onto the support on the fluid outlet pipe 42. The support for each set of balls on the uid outlet pipe 42 may consist of a plate 50, secured to the pipe 42, supporting near its periphery six brackets 51 upon each of which is rotatably mounted a roller 52. Each roller 52 supports a ball 45 when the reservoir 40 is in its raised posi? tion, as shown in Fig. 1. The series of plates 50 are ,supported at the peripheries thereof by means of vertical strips 53 which` also serve to coperate with the rollers 52 and pipe 42 to provide individual compartments for the balls 45. For each set of balls, there is provided a ring 54, supported by the rings 39 on the reservoir 40. The rings 54 are spaced apart and supported by means of vertical strips 55 which are Securely attachedvto the rings or bails Each ring 54 at its inner periphery is provided with a downwardly extending flange 56 against which the balls may rest when the reservoir 40 is in its raised position. The distance between the flange 56 and the center line of each roller 52 is greater, and the distance between the outletl pipe 42 and the center line of each roller 52 is less, than the radius of the balls 45 so that in the position of the reservoir, shown in Fig. 1, the balls 45 will be supported by the rollers 52 and will rest 52, whereupon the balls 45 roll onto the rings 54 and rest against the rollers 52, as shown in Fig. 6. The combined weight of the balls 45 is such that with the balls on the rings 54 and the reservoir in its lower position, asshown by the dotted lines in Fig. 1, it will be held there until the level of fluid in the reservoir 40 has reached a point just above the lower end of the outlet pipe 42, when the buoyancy of the reservoir will overcome the weight of the balls 45 and it will rise. As the reservoir 40 gradually rises, the balls 45 are transferred to the rollers 52, whereupon the reservoir 40 continues to rise at a more rapid rate, finally raising the yoke 35 and operating the valve levers 29 and 30 to open the exhaust valve and to close the air inlet valve. y

The fluid inlet or foot valve 13 is large compared to the areabetween the reservoir 40 and the side of the cylinder, so that when a fluid is being admitted through the inlet valve 13 and while' the fluid-is rising around will be in its lowered position, and water.

will force open the foot valve 13, admitting water to the cylinder. As water rises in the cylinder, it will, before rising to the top of the reservoir 40, reach a point at which the buoyancy of `the reservoir overcomes the weight of the balls 45', when the reservoir will rise, transferring the balls to the rollers 52, and opening the exhaust valve and closing the'air inlet valve. The water will continue to rise until it reaches the topr ofthe reservoir 40 into which it will flow until the reservoir 40 is filled, when the reservoir 40 will sink, closing the exhaust valve and opening the air inlet valve, the balls 45 being transferred from the rollers 52 to the rings 54. If at this time a source of compressed air be connected with the pipe 20 when the water pipe 21 is closed at its outer end, the only result will be the closure of the foot valve 13 brought about by the pressure ofthe compressed air within the cylinder. Now if the water pipe 21 be opened, the air pressure in the cylinder will force water up through the water outlet pipe 42, opening 19 and water pipe 21. Water will continue to flow as long as pipe 21 is open. When the level of the water in the reservoir 40 reaches a point slightly above the lower end of water outlet pipe 42, the buoyancy of the reservoir overcomes the weight of the balls 45,- and lthe reservoir begins to rise. When it has risen far enough to permit itsV upper edge to engage the, extremities of the U- shaped end of the valvelever 30, the transference of the balls l5 from the rings 54 to the rollers 52 has proceeded to such an extent that the most of the Weight is supportedby the rollers. The reservoir, therefore, now rises very rapidly, moving the valve levers 29 and 30 about their pivot points to close the air inlet valve and open the exhaust valve. The air inlet being closed and the exhaust open, the pressure of the water in which the cylinder is immersed forces the foot valve open, and the reservoir is again filled. When filled, the reservoir sinks. closing the exhaust valve and openlnx;r the air inlet valve as before explained, whereupon the foot valve 13 is closed, since a source of compressed air is connected With pipe 20. f 4

To prevent water in the water outlet pipe 42 from pouring back into the reservoir while the reservoir is being filled, an ordinary check valve G0 may be placed in the water outlet pipe 42 near itsV lower end. Y
